While the west is getting character posters for Transformers: Age of Extinction that feature the American characters from the film, it looks like China and likely other areas in the region are going to get posters that highlight the Chinese actors. In this case its Li Bingbing who plays CEO Sue Yueming who runs a company that has been referenced as the "mother of transformers" who might be making TF technology. The references are a bit unclear and they often came from translations from Chinese articles so context get garbled. Any case, she was in the trailer for a blink or you miss it moment.
